Coincidentally, I was looking through the site yesterday but couldn't find any clear details on how money is used for each of the different funds.

I've just had a quick look round now, and I'm still unsure which fund I should donate to, and precisely how the money will be used. This information may be on the site somewhere, but it wasn't anywhere I looked. How about linking to information about what the different funds are from the list of donors and the donation form?
